Give the expression for the excess pressure in a soap bubble in air. View Solution Obtain an expression for the excess of pressure inside a (i) liquid drop (ii) liquid bubble (iii) air bubble. View Solution Obtain the expression for excess pressure inside a soap bubble. View Solution द...
The surface of the liquids have a surface tension, which causes a stretch on the surface of the liquid. Because of the surface tension of the liquid surface, the drops and bubbles have excess pressure inside as compared to outside.Answer and Explanation: The smaller bubbles have more excess ...
places the liquid near the center of the body in a state of hydrostatic tension. The time required for liquid to flow from the surface to the interior is described byDarcy's law, and thus depends on parameters such as the particle size, particle packing density, differential liquid pressure,...
Why is blood pressure called excess pressure? Use the term true pressure.Mercury:Mercury is known as the metallic element, which is used as a standard fluid to measure the body's blood pressure temperature through a thermometer. It has a high density, and it is stable at room t...
and the totalin pressure P are measured during the experiment.p(ϑs) is the vapor pressure of the solution at temperature ϑs. ,D2O Cg and Cl are quantities referred to D2O, respectively, the heat of evaporation,heat capacity of gas and liquid.V is the thermoneutral potential (1.5367 ...
Step 2: Use the formula for excess pressure The excess pressurePinside a droplet due to surface tension is given by: P=2TR whereTis the surface tension of water, given asT=72×10−3N/m. Step 3: Calculate the excess pressure inside and outside the raindrop ...
A shutoff valve installed on the discharge side of a pump to automatically shutoff hazardous liquid flow in the event of a rupture on the downstream side of the shutoff valve. The shutoff valve operates in response to a predetermined pressure drop across a valve and may also function to st...
